Pipe (seamless and welded in random lengths and cut to size)
Fittings (BW and forged fittings)
Flanges (ANSI, DIN, EN, JIS)
Bar (round, square and hexagonal in random lengths and cut to size)
Forgings (Discs, Rings and forgings according to drawing)
Plate and sheet (Full plates and cut to size)
Applications Alloy 825:
Alloy 825 is a nickel-iron-chromium alloy with molybdenum and copper added to it. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking and to localized attack such as pitting and crevice corrosion. The alloy is especially resistant to sulfuric and phosphoric acids. Used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production and pickling equipment.
